Hmm, so he decided it was a segnosaur, eh? I'll really miss seeing this

Same here. Though I can picture it being both refreshing, or horrific.

Eh, I'd be suprised if it was any different than his thesis. But hey, at
least it involves "Xuanhuasaurus".

"A microsite within the basal portion of Unit VII of the Cloverly Formation
evidence of a small theropod (MOR 1178) that may be new to the faunal
assemblage thus far
recognized from this Early Cretaceous unit. Its characters are a shallowly
grooved neural platform
running along the dorsal surface of the distal caudal vertebrae, small
serrations on an associated maxillary tooth fragment, a strong sagittal
crest on the parietal
fragment, a particularly robust metatarsal IV, and 2nd 3rd and 4th pes
unguals which conform
closely to the proportional ratios found on Troodon formosus (NMC#8539). The
cross-sectional thickness of the maxillary tooth fragment is 5.8 mm. The
dorsal surface of the
ectopterygoid possesses complex pneumatic depressions. The skeletal elements
approximately 76 percent the size of the corresponding bones of Deinonychus
(YPM 5205, 5211, AMNH 3015), though the forelimbs are closer to 89 percent.
Thus the forelimbs
on this new specimen would be appear to be unusually long. The coracoid,
carpal, cervical vertebrae and pes unguals display some unique and
interesting characters that
differ from Deinonychus antirrhopus. The sagittal crest continues on to the
frontal region on
the dorsal surface of the skull. This would create a striking feature in a
Making lemonade out of lemons, it seems. :-) And we already have Ostrom's
huge monograph on Deinonychus, Nick.

Must get his thesis sometime.

Uh-oh. This is the same Yuan who coauthored Scansoriopteryx with Czerkas.
